Title: Suppression of the antiferromagnetic order when approaching the superconducting state in a phase-separated crystal of $K_{x} {Fe}_{2 - y} {Se}_{2}$

Abstract

Here, we combined elastic and inelastic neutron scattering techniques, magnetic susceptibility, and resistivity measurements to study single-crystal samples of K_xFe_2-ySe₂, which contain the superconducting phase that has a transition temperature of ~31 K. In the inelastic neutron scattering measurements, we also observe both the spin-wave excitations resulting from the block antiferromagnetic ordered phase and the resonance that is associated with the superconductivity in the superconducting phase, demonstrating the coexistence of these two orders. From the temperature dependence of the intensity of the magnetic Bragg peaks, we find that well before entering the superconducting state, the development of the magnetic order is interrupted, at ~42 K. We consider this result to be evidence for the physical separation of the antiferromagnetic and superconducting phases; the suppression is possibly due to the proximity effect of the superconducting fluctuations on the antiferromagnetic order.

Doping evolution of spin fluctuations and their peculiar suppression at low temperatures in ${Ca (Fe}_{1 - x} {Co}_{x})_{2} {As}_{2}$

Journal Article Sapkota, A. ; Das, P. ; Bohmer, A. E. ; ... - Physical Review B

Results of inelastic neutron scattering measurements are reported for two annealed compositions of Ca(Fe_1–xCo_x)₂As₂, x = 0.026 and 0.030, which possess stripe-type antiferromagnetically ordered and superconducting ground states, respectively. In the AFM ground state, well-defined and gapped spin waves are observed for x = 0.026, similar to the parent CaFe₂As₂ compound. We conclude that the well-defined spin waves are likely to be present for all x corresponding to the AFM state. This behavior is in contrast to the smooth evolution to overdamped spin dynamics observed in Ba(Fe_1–xCo_x)₂As₂, wherein the crossover corresponds to microscopically coexisting AFM order and SC at lowmore »« less

In both samples, we observe unexpected van Hove singularities in the phonon density of states at energies of 1– 2.5 meV, suggestive of local modes. On cooling the superconducting sample through T_c, there is an enhancement of these features for energies below twice the superconducting-gap energy.

We present a comprehensive set of elastic and inelastic neutron scattering measurements on a range of Fe-doped samples of U(Ru_1–xFe_x)₂Si₂ with 0.01 ≤ x ≤ 0.15. All of the samples measured exhibit long-range antiferromagnetic order, with the size of the magnetic moment quickly increasing to 0.51μB at 2.5% doping and continuing to increase monotonically with doping, reaching 0.69μB at 15% doping. Time-of-flight and inelastic triple-axis measurements show the existence of excitations at (1 0 0) and (1.4 0 0) in all samples, which are also observed in the parent compound.

Journal Article Ross, Kathryn A. ; Brown, J. M. ; Cava, R. J. ; ... - Physical Review B

The antiferromagnetic pyrochlore material NaCaCo₂F₇ is a thermal spin liquid over a broad temperature range (≈140 K down to T_F=2.4 K), in which magnetic correlations between Co²⁺ dipole moments explore a continuous manifold of antiferromagnetic XY states. The thermal spin liquid is interrupted by spin freezing at a temperature that is ~2% of the mean-field interaction strength, leading to short-range static XY clusters with distinctive relaxation dynamics. Here we report the low-energy inelastic neutron scattering response from the related compound NaSrCo₂F₇, confirming that it hosts the same static and dynamic spin correlations as NaCaCo₂F₇.
